The 24-hour curfew that had been imposed in parts of Saudi Arabia has been rolled out to all areas of five cities in the kingdom.
Tabuk, Dammam, Dhahran and Hofuf, plus the capital of Riyadh have extended restrictions on movement because of the coronavirus outbreak.
The Ministry of Interior says the curfew will last until further notice.
Restrictions do not apply to key workers in both the public and private sectors.
Saudi Press Agency reports that the order prohibits any commercial activities, except for health facilities, pharmacies, foodstuff stores, petrol stations, gas stores, banking services, maintenance and operation works, plumbing works, electrical and air conditioning, water delivery services and sewage tanks.
Residents may leave their homes to buy only the essentials within their neighbourhood, and during the period from 6am until 3pm every day.
